Washington: A recipe for how to make pressure cooker bombs, which were used in the Boston Marathon bombings, have been a frequent weapon of militants in Afghanistan, India and Pakistan, and was once published in the Al-Qaeda magazine Inspire.
Al-Qaeda's Yemen branch gave a detailed description on how to make a pressure cooker bomb in the 2010 first issue of "Inspire."
The chapter titled "Make a bomb in the kitchen of your mom," described 'pressurized cooker is the most effective method for making a simple bomb', the Washington Times reports.
The article described how to fill the cooker with shrapnel and gunpowder and to create a detonator using the filament of a light bulb and a clock timer.
According to the report, an issue last year reprinted an older article by a veteran Syrian jihadi Abu Musab al-Souri addressing would-be jihadis proposing a long list of possible targets for attacks, among them "crowded sports arenas" and "annual social events."
The SITE Monitoring Service, a U.S. independent group tracking militant messaging online, noted that Islamic extremists are not the only ones paying attention to the Al-Qaeda magazine.
White supremacists have also circulated copies on their web forums, the service said.
They found "Inspire" and "other Al-Qaeda manuals beneficial for their strategies," it added. (ANI)
